METAL TIRE-BAND.

Application filed May 16. 1912,

Specification of Letters Patent.

Patented Mar. 31, 1914. Serial No. 697,6 1].

I. 'luonis l-luanxsg andhse'lul llclal 'l it'e-liandi of which the,

following is a speeilicati it Mt invention rela es to the t-oi'istruetion of metal tire bands for the wheels ol' vehi- I eles and more particularly l'tfllll'tr to the construction o; the metal tire bands of the class used in making wheels in which rubber outer sin-lace ol the tire hand between the tires are fastened to the metallic tire bairls.

()iuobject of in inventioi is to provide a tire band ol? improved constrtu'tion having novel means on the surfaces thereof engaging wit the rubber tire whereby the rubber tire is more s curely fastened to the tire band and b which creeping or relative an gular axial movement of ill: rubber tire and the tire band is prevented and overcome.

Referring to the accompanying drawings forming part of this specification, Figure l is a plan on an enlarged scale showing the outer or lopsurfaee ot' a multiple length tire band as rolled in accordance with my invention. Fig. 2 is a sectional side elevation showing a portion of the tire band as formed when mounted on a wheel having a rubber tire secured in place thereon. the section being taken on the line ll- -ll of Fig. I}, Fig. 3 is a transverse section of the the band having a rubber tirethereon. the section being taken on the line lll---l I of Fig. 2. Fig. l is a section similar to that in Fig. 3, talcen on the line lf-JV of Fig. 2, the rubber tire being shown in outline in broken lines. Fig. .5 is a scctiot'ial side elevation similar to that shown in big. the section being taken on the line V oi. Fig. 3.

lo. the drawings. the numeral 2 designates the tire band as constructed in armor-dance with this invention, having a rubber tire 3 secured in place thereon, the tire being socured to the metal tire band by reinent or similar adhesive i.

As will be seen from the drawings, the outer surface of the tire band is provided with a series of longitudiiml ribs 5, and transwrse rib (3. The, ribs 3 are intersected bv the transverse ribs (3 so as to form a series ol' independent depressions whit-h are separated from each other:

are not oi the same height, the ribs being somewlutt lU r-i in height than the ribs 5 with which they intersect at intervals in the length ol' the rolled, multiple length tire bands. The inner surl'ace oi the tire band at the completion of the rolling operation is formed by an internualiate lla't portion 5 and by side portions fl, 9 which are angular and which taper upwardly and oulwardlv from the interme iate llat portion 8 of the inner surface ol the tire band. The bottom surfaces of Ilze depressions formed in the ribs 5 by the ribs (3 are provided with a se ries of V-shaped grooves 10 which extend lengthwise parallel to the longitudinal ribs 5 between the transverse ribs (3. The outer surlares ol: the longitudinal ribs 5 also are provided with V-shaped grooves 11 which extend lengthwise parallel to the longitudinal ribs 5 the continuity of these V-shaped indentations being interrupted at intervals by the transverse ribs 7. The transverse ibs 7 are staggered with respert to the ribs (5 and extend outward to the surface of the longitudinal ribs 5 so as to be of the same height, while the ribs o are of a height equal to about one-hall the depth of the deprestires. Pieces'o-jt the so-tormed tire bands, between the longitudinal ribs .s. The side surfaces 5 of the longitudinal ribs 5 are inclined upwardly and inwardly so the recesses or depressions are dovetailed in cross section to receive the tongues on the rubber tires. Pieces of the so-forined tire bands, which are rolled in multiple lengths are cut to length and their ends united to form annular rings of the desired diameter, the inner surface of the SO-fOl'll'MXl rings being arrai'iged to be detaehably serured on the wheels on which they are mounted.

in forming the detachable tires the rubber tire is secured to the tire band by means of cement \vhieh lills the V-shaped grooves in the bottom surl'ace of the degressions and in the surface of the longitudinal ribs 5, in this way materiall increasing the surface of the tire band. in engagement with the cement.

The side surfaces of the depressions in the tire band being tapered so as to form dovetails in cross section assist in firmly holding the rubber tire in placeon the tire band, and the transverse ribs (3 by engagel'he l p surfaces o'l ment with the end of the projections on the the ribs 5 and 6, in the tire band as rolled l rubber tire extending into the depressions,

prevent creeping or relative angular movement axially of the rubber tire and tire band.

Modifications in the construction of the tire bands forming my invention may be made Without departing from the invention, as defined in the claims. The length and Width of the depressions formed between the longitudinal ribs may be varied, the size and number of the V-shaped grooves in the bottom surface of the depressions and in the surface of the longitudinal ribs, may be changed. The cross section of the tires may be changed and other variations may be made I claim 1. A tire band comprising a flat metal band having longitudinal and transverse ribs forming a series of separated independent depressions in'pne surface thereof, and a plurality of longitudinally extending V-shaped grooves inthe bottom surface of said depressions.

2. A tire band comprising a flat metal band having longitudinal and transverse ribs forming a plurality of rows of separated independent depressions in one surlace thereof, and a pluralityof parallel longitudinally extending V-shaped grooves in the longitudinal ribs and bottom surface of said depressions.

. 3. A tire band comprising a flat metal band having longitudinal and transverse ribs forming a plurality of roWs of separated independent depressions in one sur face thereof, and a plurality of longitudinally extending V-shaped grooves in the bottom surface of said depressions, the transverse ribs forming the depressions being staggered relatively to the transverse ribs on the outer surfaces of the longitudinal ribs.

i. -A tire band comprising a flat metal band having longitudinal and transverse ribs forming a plurality of roWs of separated independent depressions in one surface thereof, a plurality of longitudinally extending V-shaped grooves in -the bottom surface of said depressions, and a plurality of parallel V-shaped longitudinal grooves at separated intervals in the length of the longitudinal ribs of said tire band.

5. A tire band comprising a flat metal band having longitudinal and transverse ribs forming a plurality of rows of separated independent depressions in one surface thereof, the depressions in one row being staggered. relatively to those in the adjacent rows, and at least. one V-shaped longi-. tudinally extending groove in each of said ribs forming a plurality ofrovvs of sepa rated independent 'depressions in one sur face thereof, and a plurality-of parallel V- shaped longitudinal grooves at separated intervals in the length of the longitudinal ribs of the tire band;

In testimony whereof, I have hereunto set m hand. a
